财神888电玩电玩888财神街机设计制造的大规格铁模覆砂铸造生产线主要针对船用车用发动机曲轴、载重车桥壳、发动机缸体等较大铸件生产而开发的,促进了铁模覆砂铸造应用优先域的拓展。主要特点是铁模的尺寸和重量大,生产线设备刚性好,机械化程度高。
那么,铁模覆砂铸造这个工艺设计主要解决了什么问题呢:
①铁模铁模覆砂铸造壁厚和覆砂层厚度及二者的配合,以满足不同壁厚和不同材质铸件对凝固和冷却的不同要求;
②便捷和经济的覆砂成型方法,以满足不同铸件对表面质量和尺寸精度的要求;
③工艺参数。如浇注系统、射砂系统、排气系统等的确定;
④批量生产的实现。例如生产线及覆砂主机和辅机的设计定型;
⑤工艺规程的制定,例如浇注、冷却和开箱等规程,以及铸件成分的调整等。
The foundry production line designed and manufactured by Zhejiang mechanical and electrical design and Research Institute Co., Ltd. is mainly developed for the production of large castings such as marine engine crankshaft, truck axle housing, engine cylinder block, etc., which promotes the development of the priority area of the application of sand-clad foundry. The main features are large size and weight of the iron mold, good rigidity of the production line equipment and high degree of mechanization.
 
So, what are the main problems solved in the process design of sand-clad iron mold casting
 
① the thickness of the wall and sand layer of the sand-clad casting of the iron mold and the combination of the two, so as to meet the different requirements of different wall thickness and different material castings for solidification and cooling;
 
② convenient and economical sand covering molding method to meet the requirements of different castings for surface quality and dimensional accuracy;
 
③ process parameters. Such as the determination of pouring system, sand shooting system, exhaust system, etc;
 
The realization of mass production. For example, the design and finalization of the production line and the main and auxiliary machines covered with sand;
 
⑤ formulation of process procedures, such as pouring, cooling and unpacking procedures, as well as adjustment of casting composition, etc.
